Fixed bug with water shader...
On topic now... :

I just noticed it drops the FPS when I'm standing right infront of a plant , and it even stretches outside my screen. Sometimes it drops the fps when I'm pointing at the plant , so I tought my crosshair entity detection function was going slow. Gonna check that now , but I've used it many times before and I've never had problems , not to mention it was on much lower spec. PCs.
Other than that , I also removed my water model from the scene during the low FPS moment and the FPS went up. I created it again and the FPS dropped again. I'm guessing thats because of too many verts and faces , but the water model is only 28x28 verts. Maby I should keep lowering my graphics quality , but this goes beyond the expected... I tested on 640x480 and 800x600 (640 displays wrong water) and it didnt lower the FPS. Lowest was 55 wich is perfect for me.
Shouldnt my PC be able to display more polys ? And I havent even added a house and other models on the island...
